import React, { useRef, useState } from 'react'

import BeforeIcon from "../assests/before.svg" import NextIcon from "../assests/next.svg"

import Banner1 from "../assests/banner1.jpg" import Banner2 from "../assests/banner2.jpg"

import "../styles/banner.css"

export default function Banner() {

const ImgContainer = useRef()

const [position, setposition] = useState(0)

const w = window.innerWidth

const handleNext = () => {
    let newposition = position+1
    let move = w*newposition
    setposition(newposition)

    return(
        ImgContainer.current.style.transform = "translateX(-" + move + "px)",
        ImgContainer.current.style.transition = "transform, 1s",
        console.log(move),
        setposition(position+1)
    )
}
const handleBefore = () => {
    let newposition = position-1
    let move = w*newposition
    setposition(newposition)

    return(
        ImgContainer.current.style.transform = "translateX(-" + move + "px)",
        ImgContainer.current.style.transition = "transform, 1s",
        console.log(ImgContainer.current.style)
    )
}

setTimeout(() => {
    if (position===0){
        handleNext()
    }
    else {
        return(
            console.log("slide")
        )
    }
}, 5000);
return (
    <section>
        <button onClick={handleBefore}><img src={BeforeIcon} alt="" className="button rigth"/></button>
            <div ref={ImgContainer} className="imgcontainer">
